SOURCE: Epson LQ-590 Matrix Printer Paper feed Problem

Assuming that you are feeding the paper into the correct end of the printer :), it seems that the printer is defective, but

First unplug the printer from the wall, wait a few minutes,
and see if it resets. If that does not work, read on.

  1. Printer rollers (and sometimes head movements as well)
    are controlled by "Stepping Motors"

    Unlike an ordinary DC motor with two wires, that spins
    clockwise or counter clockwise depending on the voltage
    polarity,

    a stepping motor contains several pairs of wires, that
    are pulsed in a controlled sequence, causing the motor
    to spin in precise angular steps. Depending on the
    number of wire pairs (poles) and internal gears, the
    stepping motor can have a resolution as course as
    90 degrees, and as fine as 0.05 degrees per step,
    depending on the cost and applications.

    Linear stepping motors can even move an object in
    a straight line.

    The benefit of these stepping motors is that, unlike a
    linear servo motor, they do not need complex positional
    feed-back for precise control, they simply step as many
    times as you tell them to. Four steps left, two steps back
    .... etc.

  2. These stepping motors are in turn driven by semiconductor switches (transistors) which are
    ultimately controlled by a central processor within the printer.

    Depending on the printer model, and how sophisticated
    the printer's internal processor is, the paper and head
    movements can be either automatically controlled by
    SOFTWARE (firmware) within the printer itself, or by the device drivers installed in Windows.

    The more self-sufficient the printer is, of course, the less
    hassle and CPU overhead on your PC.

  3. When any of the components within this chain of command fail, the stepping motor will move incorrectly:

    a) Skip steps
    b) Get stuck
    c) Oscillate back and forth
    d) Spin backwards.

  4. The causes could be:

    a) One bad wire in the ribbon connecting the motor
    to its controller board.

    b) Bad motor driver transistor: Open or shorted.

    c) Bad data line from the printer's internal control
    processor to the driver transistor array.

    d) Bad processor chip, memory or firmware within
    the printer, e.g. a burned out register or firmware
    memory location.

    e) Defective internal power supply, causing everything
    else to malfunction.

    f) Bad paper position sensor

    d) Crashed control program, which is probably the
    only thing that is fixable:

    i) unplug the printer from the wall socket, wait a
    few minutes, and see if it resets.

  5. It is also remotely (theoretically) possible, that
    the Window drivers are corrupt but this is very unlikely.

  6. If you are fairly brave and want to take the printer apart, and have some electronics knowledge and a few basic instruments, probe the roller drive motor wires, and see what gives. Is one wire stuck consistently low or high ?

    Is one of the motor windings open or shorted ?

    Is one of the driver transistors fried ?

    This very much depends on your level of skill, and the test equipment you have to work with. If you don't have a decent oscilloscope you will not get far. Without a digital multimeter you will not get anywhere at all.
Also do not forget that printers are dirt cheap, less than the ink when it runs out, so this may not be worth your time and effort.

Call the manufacturer, scream blue murder, accuse them of setting your house on fire and giving your dog diarrhea ....

and see if they will send you a freebee.

Hope this explains it.
Please rate my answers.

SOURCE: Epson DX 6050 Paper feeding issues

Hi,

I'm here to FIX your problem. I don't want to be helpful. I want to FIX your problem. If you will work with me, I will work with you until this is FIXED.

The paper not loading from one side is a problem with the pickup and feed roller on one side. This happens when rollers dry out and actually shrink as a result.

To resolve this, all we need to do is 'rehydrate' the rollers. There are solutions you can buy to do this and maybe it will come to that with yours. But, I've used this method below for years of working on Ink Jets since they first came out in 92.

Remove all paper.
Get a clean sponge and dampen it fairly well.
Now, you will want to repeatedly press the Paper Feed button while holding the damp sponge firmly against the pickup and feed rollers you can see while looking down your paper tray of your printer. You should be able to see these rollers quite easily.

The trick is to keep damping the sponge and pressing it against the rollers while pressing Paper Feed a lot of times. How many times? Well, this varies. But you will want to do this at least a dozen times on each side of the pickup rollers to start with.

Once, you are done with this initial attempt, you will want to give the rollers a chance for their surface to dry to the touch. Then, insert a full load of paper and press Paper Feed and see if your printer loads the paper correctly. If it attempts to load and does so better than before but does not quite finish, pull the paper out, its okay to do this, and rehydrate the rollers some more until the paper feed works as expected.

Let me know how this works out for you. I can direct you to a vendor on the internet to buy some roller rejuvenator later if its actually needed. I have found that you can do this trick with the damp sponge on an as needed basis from time to time and achieve the same result.

If, however this does not make any difference in your printers ability to pick up and feed paper then you have a mechanical problem and if under warranty you'll want Epson to fix it. If not under warranty you could have Epson fix it but you'd probably be better off getting a replacement. You will have to decided on that once Epson quotes a price to repair and replace the damaged parts.

Please use the comment text area below to communicate with me and ask any questions to explain something or ask a further question. I will receive an email alert and will get back with you as soon as I am able. This will depend on our time zone differences.

Regards,
Worldvet

SOURCE: Epson Sx200- Paper wont feed

Just a thought,as I had a similar problem.The instructions are abysmal,but it may be worth having a look where you feed the paper in and squeezing the grey plastic gizmo,and moving it to the left to allow the paper to enter the feed properly.

SOURCE: paper will not feed into printer epson r300 printer

This is a common prob of all epson printer. If you use more than 230GSM thickness paper with the printer and use 80 gsm paper next, it wont pick up. This is due to the spring in the back side of the paper picker unit elangated to more thickness and fail to function fully. you can remove the paper pickup unit and change the spring if you have the service manual.

When I insert the 4x6 paper portrait it won't advance it to print.


You are probably using a glossy paper or photo paper 230gsm or above, some printers are having a hard time feeding with those kind of papers, try using lower than 230 gsm.
